Title: Improvements relating to agitating apparatus, particularly for dry-powder mixing
Inventor: CHEYNE ROBERT DOUGLAS
IPC: B01F15/00
Filed: 1955-10-18
Abstract: 800,384. Agitating apparatus. COLEMAN-WALLWORK CO., Ltd. Oct. 12, 1956 [Oct. 18, 1955], No. 29681/55. Class 86 [Also in Group XXIX] Apparatus for mixing dry powders, for example, the materials used for making shell moulds for casting purposes, comprises a casing 1 enclosing a pair of agitating elements 2 each composed of two castiron side plates 4 connected together by a plurality of stainless steel 1 rods 5 5 extending between the peripheries of the said plates and parallel to a shaft 3 so that they interengage as the elements of a Rootes blower. Rubbertipped scraping strips 6 which engage the inside of the casing 1 are carried on the extremities of the elements 2. An electric motor 8 drives the agitating elements at about 100 r.p.m. through reduction gearing contained within a housing 9 and through a coupling 10. Compressed air enters the apparatus at 37 and passes through traps 39, 40 to a junction piece 41 from which one pipe 42 leads to a vibrator control valve 22 and another pipe 43 leads to a two-way main control valve 44. A handle 45 is provided on the two-way valve 44 to control the supply of compressed air through the pipes 46, 47 to either side of a piston in a cylinder 33, the piston being connected to a plug 29 closing the outlet 28 of the mixer so that operation of the handle 45 controls the discharge of the mixed material into a conduit 36. Material enters the casing by an inlet pipe 13 from a hopper 14 the neck 19 of which houses a vibrator and has a stop-cock valve having a handle 20 which co-operates with a plunger 22a of a valve 22 to control the air supply to the vibrator so that the vibrator and stop-cock valve operate together. A pressure relief valve 23 is mounted on the side of the casing 1 and is connected to a junction piece 48, a regulating valve 50, a non-return valve 51 and a pipe 52 leading to an inlet pipe 15. On charging the apparatus the handle 20 is lowered and air displaced from the inside of the casing by the incoming material escapes through the pressure relief valve 23 and pipe 56 terminating in a filter 57. When the apparatus is charged the stopcock valve is closed and the vibrator stopped and the electric motor 8 is started. To discharge the mixed material the main control valve 44 is set to lower the plug 29 and compressed air is delivered through the regulating valve 50 to a connection 16 at the top of the mixer to blow out any material remaining in the casing. At the same time compressed air is delivered through a pipe 49 from the junction piece 48 to the pressure relief valve 23 forcing a piston inside it to seal off the interior of the casing from the atmosphere. More than one hopper may be used to charge the apparatus through inlets 15, 17 with various materials to be mixed. When they are not being used the inlets are closed by screwcaps 18.

Abstract: 232,648. Kynnersley, T. R. S. Nov. 27, 1923. Pneumatic springs; buffers.-In spring suspensions for road and railway vehicles, a lever connected to the body and to the axle is adapted to pivot about either part and to compress a pneumatic cushion capable of lateral extension in such a manner that as pressure exerted on the lever, due to relative movement, increases, the contact area between the lever and pneumatic cushion increases. In Fig. 1, a pneumatic cushion 6 is interposed between the chassis 9 and a lever 4, which is pivoted to the chassis and connected by a link 3 with the end of a laminar spring 1. In the form shown in Fig. 6, the pneumatic cushions 6 are arranged at the end of a laminar spring 1, and in some instances the free end of the lever 4 may be guided and spring controlled. The pneumatic cushions of all the axles or wheels may be connected to a central air supply, and they may comprise flexible outer coverings and separate inner containers, and may be cylindrical in shape with hemispherical ends. They may be attached to the chassis by an undercut portion 19, Fig. 8, and a removable plate 20.

Title: Improvements in or relating to electrical power systems
IPC: H02P9/00
Filed: 1928-10-18
Abstract: 299,054. Associated Electrical Industries, Ltd., (formerly Metropolitan.Vickers Electrical Co., Ltd.), (Assignees of Storer, N. W.). Oct. 20, 1927, [Convention date]. Regulation, automatic; electric power transmission systems. - In a power-transmission system comprising an engine, such as a Diesel engine 10, driving a generator 13, automatic regulation of the driving torque is performed by an electro-magnetic apparatus having stator and rotor windings 22, 23 carrying currents proportional to the field and armature currents of the generator. Increase of torque in the regulator opens a switch 33 which adds a resistance section 92 to the circuit of the generator field 16; decrease of torque short-circuits the resistance 92. The periodic introduction of resistance thus tends to preserve a constant demand torque notwithstanding variations in the electrical output of the generator. In the arrangement shown in Fig. 1, the generator feeds a traction motor 68 and is provided with a separate exciter 14. A drum controller 44 makes the required circuit connections for initially starting the generator as a series motor supplied from a storage battery 20, and thereafter running it as a separately excited machine to feed the working motor. The automatic regulator or torque governor is constructed, as shown in Fig. 2, like a motor with a fieldwinding 22 and an armature-winding 24. The motor carrying the armature-winding works against adjustable springs, and can be further adjusted by setting it in different initial positions, in order that the working may be made to suit generators having different characteristics. Curves illustrating this feature, and illustrating the effect of varying the proportion of the annature current of the generator flowing through the winding 23, accompany the Specification.

[Class 38 (iii).] Motors M1, M2 are supplied with constant current from a commutator machine MD connected to the line. For motoring, the connections are as shown, but for regenerative braking the connections of the motors to the primary or secondary brushes of the machine MD are interchanged. Alternatively, the current in a variator winding on the machine MD may be reversed, and the motor connections left unchanged. The Specification as open to inspection under Sect. 91 comprises also an arrangement for exciting the field winding of a traction motor from an exciter having opposed field windings energized by the motor armature current, and by a separate source respectively, the separately excited winding being variable in direction and magnitude to change the direction of current in the motor armature, and thereby effect regenerative braking. This subject-matter does not appear in the Specification as accepted.
